Description: The invention relates to a modular rack, in particular for a device and cable cabinet.

Racks for electrical distribution components, such as stand distributor, racks, server racks or cable cabinets, or distribution cabinets, which are suitable for receiving the many cables and components, such as. In computer rooms or as the center of a network, are known. They may be coolable if necessary. The market offers so-called 19-inch racks and 19-inch cabinets. Cabinets can have a cabinet body for accessibility and for air conditioning, and a door at the front and possibly at the back. In these cabinets or racks are then attached to carriers hardware such as switches, routers. Servers, couplers, patchboxes, racks, power supplies, UPS and the like, as needed for networks.

The distributors or racks are available with and without doors, side walls, air conditioning. For higher quality or more complicated cabling and distribution cabinets are used, which are also lockable, allow unauthorized access and especially a controlled air flow.

Central component of the distributor, racks or cabinets according to the invention is a single truss-like rack system, in / on the patch panels for fiber optic and copper, servers, cables, connectors, etc. ordered - eg. By screwing, gluing od. Like. Are attached. Depending on the requirements, a housing can be built around this rack rack and this can be converted into a cabinet which, on the one hand, permits air conditioning in the manner of a climate cabinet and, on the other hand, reduces unauthorized access and soiling and dusting of the partially electrostatically attractive components.

The known racks / racks, which may be configured as server racks, switch racks, head stations, etc. - or network cabinets - allowed to keep order and clarity in the component and cable arrangements, but they themselves were not variable. Thus, when changing or extending the network architecture that used more cables or new components with different masses, a new rack or cabinet was needed. All the components of the distributor / distribution cabinet had to be replaced. Previous racks / racks / cabinets were also delivered in a few large items, which are problems during transport. These are built specifically for each product, unchangeable and therefore not suitable for product change. The modular rack according to the invention allows the installation of all available on the market hardware, even the older generations. It is e.g. possible to mount several 19 inch girders at different depths. Previous racks allowed only a given depth and when using longer components (the width of the racks is standardized, for example, by the 19 'technology) had completely new, deeper racks are used, resulting in a complete reinstallation of the system.

The known distribution / distribution cabinets also led to significant time losses during the reinstallation. They led to unwanted waste of material, as each time an extension and change in network distribution took place, a completely new distributor-carrier rack arrangement / cable cabinet had to be procured. It is also problematic that heat dissipation / cooling is required in distribution cabinets / racks with components of high electrical power of the components.

So far, for example, from W02010100115 A1, WO 2012025112 A1 method for controlling an air conditioning system for a data processing system having a plurality of distribution cabinets, known. It is in the cabinets a cold aisle, which is foreclosed against a warm aisle, provided. From an air conditioner, the warm air is sucked in, cooled and blown into the cold aisle and promoted by the electrical components in the warm aisle or the environment, the disclosure of which is referred to as prior art. 1/32

p. The known distribution cabinets / cabinets were not sustainable adaptable to new circumstances. An expandability was not given. In particular, air-conditioning manifold assemblies were not retrofittable to alter the cooling gas flows (e.g., laterally rather than from the floor or from the ceiling). The cabinet size was fixed and could not be changed, ia. otherwise the necessary tightness between hot and cold aisle was eliminated. Thus, was wasted valuable resources by constantly new distribution / cabinets.

It is therefore an object of the invention to avoid the disadvantages of the prior art. The object is achieved by a modular rack with the features of claim 1. Advantageous developments emerge from the dependent claims.

An inventive modular rack, especially for a device and cable cabinet, has u.a. the advantages: In the depth extendable several 19 "levels can be arranged in depth in front of and retrofittable an air flow control for front and side cooling can be pre-installed and retrofitted via air baffles generally retrofittable

convertible

All parts of the rack are compatible with one another. A rack according to the invention comprises: at least one front roof truss frame part (12) which can be extended in length in the form of a rectangle open at one side with fastening means; at least one longitudinally expandable front floor truss frame member (12) in the form of a side opening rectangle (12) with attachment means; at least two beams (16) extending between the front roof truss frame part and the floor truss frame part for connecting the roof frame part and the floor frame part and fixing EDP components that are detachably and displaceably secured to the front of the floor truss frame part and roof truss part ,

Advantageously, two substantially U-shaped bent cooling channel dividers (19), the side of the carrier (16) can be fastened and laterally the carrier (16) each form a unilaterally open in the front direction cable and cooling air duct, which in the rear direction substantially are closed air flow tight, provided, wherein upon supply of cold air in the front region of the rack, a passage of the cold air is prevented laterally past the baffles. Reference is made to Figs. 16-21 for air flow. This simplest embodiment enables a free-standing rack for computing components.

For applications with longer lengths or high weights, such as. In server racks can also rear roof frame (15) and rear floor frame parts (13) fastened therebetween with rear carriers (18) for computer components to the Front roof frame and front floor frame parts (12, 14) are connected.

When it becomes necessary to expand the rack in depth due to further components to be accommodated, roof frame part and floor frame part extensions (for depth extension of the rack to the roof frame part and the floor frame part (15, 13) can be provided between the roof frames These can also be provided already in the frame parts in the form of telescopes and can be extended if necessary.These extensions allow a cabinet to be extended in a simple manner without additional installation by additional components and the previous two-thirds

Rack / cabinet parts can still be used.

In the rack according to the invention, at least one floor truss frame part and a roof truss frame part extensions, such as telescopes or extension pieces have to depth extension whereby a simple depth extension or shortening of the rack or cabinet is possible.

If statics problems wg. high weight or long length occur in the rack, a vertical mounting frame (10) between the roof frame and bottom frame parts (12, 13, 14, 15) can be installed.

If it is desired to have a self-contained rack - also referred to as a cable cabinet - to the existing rack on the carriers and the frame members (12, 13, 14, 15, 10) to form a cabinet final elements selected side, ceiling, floor rear panels or front doors and horizontal cable duct members (20, 21, 22, 23, 24, 26, 50) and at the front support (16) and fixed cooling channel dividers (19a, 19b) closing plates for the ducts and combinations thereof. Typically, these termination components are screwed on, but they can also be clipped, od over spring connections. Like. Be attached.

When cable routing from one rack to another rack is desired, at least one horizontal cable channel member (50) having cable entry openings (51) at the level of the cooling channel divider panels may be mounted in the cable channel openings of the front truss frame members (12, 14) from the Kühlkanaltrennblechen, which also act as cable ducts to continue exiting cable ends.

It may be necessary that a rack according to the invention is connected to at least one further rack in a row, wherein the inner side walls (20) and the Kühlkanaltrennbleche (19b) are shortened to form a common front gas space between the adjacent racks. As a result, a common front gas space is formed which extends from the frame part front of the rack to the component level, ie the area in which the electrical components (patch panels, etc.) are fastened between the carriers. As a result, cooling air can be circulated in the common cold air flow space and passed through the carrier openings with the electrical components. It then flows through the components and emerges warmed up behind the components in the hot air area of the cabinet. From the hot air area, it can then be removed in the usual way - for example, be deducted or routed away.

It is possible to allow cooling air supply in the common air flow space laterally and / or frontally and / or via a cooling air supply from the ground, roof, whereby the spatial and technical conditions can be accommodated flexible.

One way of thermal management in such racks is that several racks are housed in at least one row arrangement in a common air conditioning housing, which has hot air outflow and cold air flow. There, it is not necessary to provide individual cabinets, but it can be put into open racks, which prevent with cooling channel dividing plates a passage of cold air laterally past the carriers. Also important is the sealing of the outdoor cabinets against the wall of the enclosure. Thus, in such an arrangement, a cold air flow from the rack front to the rear of the rack without provision of individual cabinets or a mixture of cold and warm air done, which can be reintroduced in any way in the common front gas room - depending on the circumstances using side coolers, Roof coolers or a cooling floor. It can be saved as individual cabinet doors and thus also Rangierraum be won. The cooling air can be supplied by compressed gas lines or fan arrangements which guide the cooled air into the front gas space.

If foreign components are to be provided in such a series arrangement, which have different dimensions than the racks according to the invention, they can also by 3/32

Custom made fitting plates can be inserted into the air conditioning housing.

In air conditioning of the rack, it is always important to conduct cooling air flows efficiently. For this purpose, front baffles between the side walls of the rack and the front support frame are mounted so that a passage of cooling air between the uprights and cabinet sides is closed and air flow is essentially only possible through the inside of the stand over from the front to the rear. The cooling channel dividing plates are preferably designed as cable ducts which are open at least on one side and in which (closable) openings for cable passage are formed.

It should be distinguished whether they are dividers for extension walls or dividers for end walls. Dividers for end walls preferably extend on one side to the front of the cabinet and thus include the cooling air flow. Partitions for partition walls have shorter end walls, which leave a passage to the adjacent cabinet open, so that a common frontal cold gas channel is formed.

Even with an arrangement of many racks side by side or opposite a common frontal cold gas space is formed, can be introduced into the cold air from various sides and sources and can only pass through the frame openings and the electrical components therein.

The front air flow space thus formed can receive the cooling air necessary for cooling from any desired side - it can laterally via a side radiator, laterally from the adjacent cabinet front air flow space; be supplied from the roof via a roof radiator, from a cooling bottom from below in a conventional manner.

In adjacent racks / cabinets cable between the individual cabinet / rack components over the roof with a roof duct or over the floor via a bottom channel can be performed substantially cool air-tight.

Cooling air can be introduced into the front air flow space in a conventional manner laterally via side cooling air supply and / or floor cooling air supply and / or roof cooling air supply and circulated through the support frame in the rear direction of the rack, wherein the cooling air absorbs heat from components mounted in the carriers and in the rear direction heated dissipates.

Between the stands, the patch panels, servers and other electronic components are attached, which at least partially require cooling. Through this, the cooling air sweeps from the cold front air flow space (cold aisle) to emerge as warm air (warm aisle) behind the patch panels into an aisle. The aisle is formed by the floor and truss elements, if necessary rear wall and side walls. The heated air received in it can be removed from it via the roof or in another known manner. The fact that due to the design no heated air can repel in the cold aisle, an extremely efficient cooling is achieved.

For large amounts of heat, the discharged hot air can be passed through a heat recovery device.

The fact that now a modular optionally einhausbares rack that can possibly be upgraded to a closed coolable cable cabinet device is created, arranged in the cable and components clearly arranged and accessible from all sides can be fastened and routed, it is possible to have an easily changeable and adaptable to new conditions cable and component ordering device at considerably less space. Due to the expandability of the arrangement due to its modular design, it is also possible to extend the device in any way or to increase or decrease, whereby their applicability, handling and environmental friendliness and sustainability is considerably increased due to reusable components and standardized components.

Surprisingly, by the construction according to the invention in retrofitting 4/32

Sstsntichfeches (Meiitarct AT 13 912 U1 2014-11-15 an existing cold and hot aisle are retained and possibly only the temperature control in terms of larger capacity or the like. Be converted accordingly.

Preferably, at least one support frame has lateral cable guiding and securing means for ordered streamlined lateral flat attachment of patch cables to the side walls. As a result, the cables are kept out of the cooling gas main flow and it can be avoided that turbulence takes place in hot air around cables, which could affect a smooth rapid removal of the heated cooling gases and lead to increased flow resistance. Any device carrier for parts such as cable lugs, socket strips, junction boxes, sensors, limit switches, lighting, etc. can be mounted on the front support frame. Various embodiments of the uprights can be provided - square, rectangular and angled supports can be mounted or retrofitted to the roof truss frame parts and floor truss frame parts throughout the truss.

Since a cabinet arrangement or enclosure of the racks preferably has a hot air exhaust duct, thereby the hot air can be deducted. By active stripping (active conveying elements, such as fans, pumps) can be improved with increased cooling air flow cooling. In the hot air exhaust duct, for example, the residual heat can be measured or recycled. Thus, the heat generated by the computer components and possibly also by the active cooling elements can be used to save energy in the building - for example. be fed into the heating circuit or used for hot water.

Preferably both the front roof truss frame parts and the rear roof truss frame parts and the front floor truss frame parts and rear floor truss frame parts can be exchanged under extension or shortening of the rack cabinet / or their side sections can be extended by telescopes or attachment pieces. Thus, the remaining cabinet elements can be used, a complete complex and error-prone dismantling of the rack / cabinet avoided and a sustainable distributor / cabinet construction can be achieved.

Through the rows of holes in the frame parts a variety of patch panels and shelves can be attached, so that optimum flexibility of the device and cable support device for introducing devices such as voltage stabilizers, couplers, patch panels or the like is possible.

The perforated plates also allow retaining devices to be provided by the devices extending cables until they can be introduced into the cable channels and thereby to ensure an increased level of security for the cable run. Particularly preferably, the cables are arranged by means of cable clamps arranged on the cabinet wall with release of the central area tightly packed and arranged to allow a free and unhindered as possible air flow and the accessibility or installation of other components.

On the supports 16 are usually cable distribution facilities, patch panels u. Like. - Here in 6/32

Preferably, the rear and front parts are formed so that their open ends by extension pieces (not shown, indicated by arrows) are extendable. Possibly. The front frame parts 12 a and 14 a in their open side frame sections openings for parallel to the front extending cable channels 50 have. A suitable cable duct part 50 is shown in FIG. The cable duct part can run parallel to the front, supported by the front frame parts and have openings 50 for the entry and exit of cables (not shown). For particularly heavy and long rack arrangements, such as for example for a server rack, as shown in Fig. 1b, a mounting frame 10 extending in rack height, between the floor and roof frame parts are detachably installed and also more tail Support 18 for components as shown in Fig. 1b. The frame parts 12, 13, 14, 15 can - as shown in Fig. 2, be attached to the mounting frame 10. By extending the front or rear floor and roof frame parts by means of extension components (not shown) is a depth extension of the cabinet (eg. For installation of other components) possible without replacing the entire cabinet and its installation. This is indicated by the double arrow in the rack bottom area of FIG. 19 a and also in FIG. 3. In Fig. 2 it is shown that between the bottom frame and the roof frame on the side walls of the front floor frame, the front support relative to the front truss frame parts 12, 14 are mounted reset, so that a space between the carrier 16 and front for Kabelrangieren is formed. Lateral cooling channel dividing plates 19a, 19b, which allow cooling air passage only between the supports 16 and in no case laterally thereof, can be provided on the front supports 16 (see Fig. 3). By attached to the front support 16 of FIG. 3 Kühlkanaltrennbleche 19a, 19b - here with cable grippers - a semi-closed cooling channel in the cooling channel separation plate is limited (better seen in Fig. 4), in the cabinet from the front to the front supports 16 through the Defined on the carriers separating plates 19 is defined. The baffles 19a seal against side walls and enforce in a single cabinet a course of cooling air through the (not shown) components between the carriers 16, whereby a kickback / mixing discharged heated air mixed with new cold gas prevents and the cooling efficiency is increased.

In Fig. 3, the thus assembled rack truss structure is shown in perspective, with a possibility extension to the rear ("depth extension") without affecting the assembly is indicated in front of the mounting frame. Such depth expansions are necessary, for example, when installing modified design of other servers.

Figures 3a and 3b show the cooling channel divider plates 19a and 19b which are attached to the front supports 16 and form an open cable channel 60 which seals against cooling air passage on the rack side wall. The cooling air can not pass through the demarcated by the baffles 19 cable channel and is therefore forced to pass through the opening formed between the front supports 16 and therein (not shown) components. In one embodiment, the Trennblechel9a for the cable channel from the side of the carrier in wstl. U-shaped - if a lateral connection of another cabinet and a common wiring is planned, the inner side of the U-shaped partition plate 19b may be shortened, which form with corresponding counter-shaped dividing plates of the next cabinet another, closed against cold air passage cable channel.

In Fig. 4 is a horizontal section through the rack truss structure of Fig. 3 is shown. Clearly recognizes the rear-tight channel in the front cooling channel partition plate 19a; which seals off against a side wall (not shown) and forces a cooling gas flow from front to back. It can be seen on the rear support 18 that, in this embodiment, it too is shaped so as to seal against the outflow of heated cooling air.

Fig. 5 shows the arrangement of Figs. 3 and 4 with attached side walls 20, a laterally unfolded final strike plate 21 for the cable channel in the cooling channel separating plate 19a and a wstl in the wstl. U-shaped cooling channel partition plate 19a on the front support 16 which can also serve for receiving cables, the gas-tight walls of the Kühlkanä- 7/32

Immediately paifiKta ^ i AT13 912U1 2014-11-15 le / hot air ducts are specially highlighted. Clearly recognizes that the vertical support 16 via the channel 60 forming U-shaped dividers 19 a each seal against the side wall 20 and thus force an air flow through the carrier 16. This is shown schematically in Fig. 6, which shows schematically the cold aisle and warm aisle in a rack assembly of Fig. 5a in the flow of cooling air into the cold aisle.

In Fig. 5b, a rack for attachment to an adjacent rack is shown schematically. It is clearly recognizable that the cooling channel separating plate 19b is designed for the inner wall so that it forms a common cooling channel with an adjacent cooling channel separating plate 19b of the subsequent rack together.

In Fig. 7a, the embodiment of Fig. 5a with side walls 20 is shown. It can be clearly seen that the side walls 20, which are indicated here in a transparent manner, rest on the respective cooling channel separating plates 19a and thus prevent the passage of cold air from the rack front between the carriers 16 and the respective side wall 20.

A corresponding cooling air flow is shown in Fig. 7b. There you can see how cold air flows perpendicularly to the rack front in a rack, pressed in the cold aisle through the components (not shown) and cooled in turbulent flow to the carrier 16 and leaves the warm aisle towards the rear.

Fig. 8 shows the flow in a double cabinet with side radiator. The cold air is injected from the side radiator into the common cold aisle of the cabinets arranged next to one another and passes through the components (not shown) fastened to the supports 16 without passing the supports since the cooling duct partitions 19 prevent this.

The cooled air is guided in this lateral flow in a circle - the heated air is sucked from the hot aisle, cooled in the side cooler and introduced into the common cold aisle.

Fig. 9 shows the arrangement shown schematically in Fig. 8 in a perspective view.

In Fig. 10, the cooling is explained by means of roof cooler. The cooling air is passed from the roof cooler in the channels of the cooling channel dividing plates and leaves them at the bottom of the cold aisle to strike through the components and to flow out of the warm aisle upwards.

Fig. 11a shows an arrangement of several cabinets in two rows, which are arranged on a central aisle. By means of front coolers cold cooling air is blown in the direction of the rack front, interspersed there to cool the components and is heated from the hot aisles again sucked into the cooler for cooling and use as cooling air. Front doors are unnecessary in this arrangement, if there is a common housing, as indicated for example in Fig. 11b.

Fig. 12 shows a similar arrangement of housed rows of racks, wherein the cooling air supply comes from a raised floor below the racks, which flows to the front. In this case, the heated air can not be returned, but is deducted via a trigger upwards.

Figs. 13a and b show a rack row arrangement with foreign components of other dimensions. These can be fitted into the architecture by means of matching elements / fitting plates so that the advantageous cooling air flow from the rack front to the rear remains ensured without the mixing of cooling air and warm air.

Figures 14 and 15 show a detail of the vertical floor and / or roof cable duct 60. The cables routed to the cable ducts 60 of the cooling duct divider panels 19 may be routed via the rack roof or rack floor to adjacent racks. For this purpose, the cables from the cooling channel separator plate channels 60 enter a vertical tray-like cable channel element 50 (see Fig. 15a) attached to the ends thereof with cable passage openings 51, on which they can be guided to the next cabinet. The tray-type vertical cable duct element 50 is shown in perspective in FIG. 15a. FIG. Clearly recognizes the cable passage openings 50, in which optionally the cable channel 60 of the cooling channel dividing plates ends. In this embodiment, the hot air is withdrawn from the hot air duct upwards.

Thus, the invention is a novel modular equipment rack system that serves to protect, support and dispose of network components and cables, but is much easier to handle than previously used rack systems, is easy to expand and cool well and is characterized by a significantly lighter construction and also transportability.

The variability of the air duct in various rack arrangements according to the invention is shown schematically in the following FIGS. 16 to 21. Fig. 16 shows schematically the air duct on a single rack with front ventilation, Fig. 17 shows the embodiment of Fig. 16 in another embodiment with front and side ventilation, wherein the cooling air is also guided laterally by components.

Fig. 18 illustrates the cooling air flow at side and roof cooling on a single rack, and Fig. 19, the cooling air flow in side and front cooling at the single rack of Fig. 18. Fig. 20 illustrates the cooling air flow in a double cabinet with page cooler; and FIG. 21 shows the cooling air guidance in the double rack of FIG. 20 with side and front coolers. The great variability of the racks according to the invention can therefore be estimated from FIGS. 16 to 21, although these illustrated embodiments can by no means cover all possible combinations of air ducting through a plurality of cabinets.
